Nature water recovery

My contribution is to try to help the slum giving a simple idea, trying to save as much as possible, using nature as a tool.

EXPLAIN YOUR IDEA

My idea is to take advantage of the waterborne nature strength to be consumed. Nature is a great source of water, so we can use it for waterborne, not only the slant of the rain, as the plants of their environment. However this water is often not fit for consumption. There needs to be a system that cleans the water and make it drinkable. And how can we do this? Creating a utilization system of rainwater or even a solar distillation system. The utilization system of rainwater consists of a home water filtration system. This filtering of waterborne consists of five layers: the first is stone; the second sand, the third and fourth is the repetition of the first two and the last is charcoal and then we have safe water. The solar distillation system is to deploy a basic system of underground waterborne harvest, a soil located in a wetland area that receives sunlight for most of the day. This requires digging a hole in the ground where it puts foliage and a container. The plug the hole is a plastic film with a stone to make weight. Because the leaves are at a very high temperature, owing to the sunlight passing through the plastic and let not breathe, they begin to release tiny droplets of water that turn into vapor and then in liquid, H2O. To turn that water into drinking water need a pump to draw the water until the water filtration. This filtering process is the same as mentioned above. With this idea I think I can contribute to help localities with drinking water shortages.

WHO BENEFITS?

Poor communities and urban slums in high density area of rain. Poor communities and urban slums who live in areas where it is scanty the existence of drinking water. Contributed to the water storage in urban slums, where it is observed the shortage of water due to droughts.

HOW DOES YOUR IDEA TAKE INTO ACCOUNT THE CONTEXT OF URBAN SLUMS AND CLIMATE CHANGE?

In high density zones rain, there exists the possibility of flooding, so my idea contributes to reducing these floods. However in areas where there is often dry, my idea enables the reuse of water from nature and storage of collected water, to thereby decrease the water shortage in these areas.

At this time, I am master student in product design. I do not have a great knowledge in this area but I have always been interested by the social area and how can I help make people's lives better.

Interesting idea. How much space is needed for this system? How much would it cost to set it up and maintain it?

Already I apologize to delay answer, but here are the answers to the questions raised.

1- How much space is needed for this system?
The space is relative because it will depending on the hole size of the solar distillation system. However, to get an idea of how much space is needed for this system, I give an example: If the system is in proper location for their operation and has the hole 900mm wide and 600mm deep, this system can produce up to a liter of water per day. Besides that planting vegetation into the hole helps to create more moisture.
For the whole of the systems is required a space that has two pumps, a water container, a filter and a container for rain water storage and the other for clean water. After a survey of the size of the market products made some approximate calculations and it takes more or less an area of 792,135m2.

2- How much would it cost to set it up and maintain it?
To answer this question had to do some research to find out what exists in the market. It is important to note that I am Portuguese and that some of the products researched are Portuguese or are part of Europe. However I made a calculation of how much is likely to cost and is around 2430.41755R$. Will be able to come to cost a little more. Given that mud, vegetation, foliage, sand and stone can be found in nature, that is not necessary to purchase.
In terms of maintenance it is necessary to change the foliage when they no longer produce water, such as, the change is necessary to the charcoal, stones and sand used in the filter.

I hope that answers to the questions, because I have not much experience in this area.
